DIY kit: 65 gal

DIY kit: 65 gal


Build your own Rain Bench® that holds 65 gallons of water, and 2 people.

(the water in, the people on)

The actual capacity of the liner that is included is up to 140 gallons, which means if you simply build a bigger box, it will expand to the size (maximum 32″L x 32″W x32″h) and hold a ton of water.

Ok, it will only hold 1,120 lbs, or a little over half ton of water if built to max capacity.

That’s a lot of water. (Tip: If you want to put one on your deck, make sure it was built to hold a hot tub. We recommend setting it on a level bed of permeable gravel instead)


RainBench DIY kitThe Original Rain Bench® DIY kit, this one allows you to take one sheet of plywood, a few sticks of lumber and turn it into a nice little bench that you can paint any color you like, store water in and sit down on.

Save Water, Just by Sitting There.

The RainBench® DIY Kit is a rainwater harvesting system for someone with basic carpentry skills.  Save $ on shipping.  You supply the lumber and labor to build a bench that acts like a rain barrel with 65 gallon capacity. Buy lumber & hardware locally (usually ~30-40)

Detailed instructions in this kit help you build a 36″L x 21″H x 28″W bench that holds 65 gallons of rainwater or greywater.  (liner can be customized to hold up to 140 gallons)

PLEASE NOTE:  The brass fitting (pictured above) and one of the others have been replaced with a more efficient direct garden hose adapter.  Works the same.
